Data classes (OO Python Tutorials)

Lesson 05 - In this video, you will learn how to use data classes, which are a new and convenient feature of Python that simplifies the creation and usage of classes that mainly store data.

A data class is a regular Python class that is decorated with the @dataclass decorator from the dataclasses module. A data class is designed to hold data values and provide some basic functionality for working with them, such as initialization, representation, comparison, and copying. A data class can also have methods, properties, and class variables, just like a regular class, but its main purpose is to store data.

To create a data class in Python, you need to import the dataclass decorator from the dataclasses module, and use it to decorate a class that has fields. A field is a class variable that has a type annotation, which is a way of specifying the type of the variable using the colon syntax.
